Abstract

The electric motorcycle is one type of transportation that is suitable for urban activities. Electric motorcycles use batteries as an energy storage component to store electrical energy. Lithium-ion batteries are generally used as the battery packs used in electric motorcycles. There are various types of lithium batteries that have different characteristics and performances. In general, electric motorcycle use batteries with small dimensions and have a high energy density such as the NMC type, or batteries with a high number of cycles such as the LiFePO4 type battery. The different batteries will produce different heat characteristics, with an optimal working temperature of 15-35 C. When the battery is used there will be an increase in temperature due to chemical reactions that occur in the battery cells. This paper will further discuss the characteristics of the battery pack when used at different temperatures in real use. The use of different types of batteries has different characteristics when facing an increase in temperature. NMC batteries have faster SOC reduction and higher heat generation compared to LFP.

电动摩托车NMC和LiFePO4电池组的产热实验

电动摩托车是一种适合城市活动的交通工具。电动摩托车使用电池作为储能部件来存储电能。锂离子电池一般被用作电动摩托车的电池组。锂电池有多种类型，具有不同的特性和性能。一般情况下，电动摩托车使用尺寸小、能量密度高的电池，如NMC型，或循环次数高的电池，如LiFePO4型电池。不同的电池会产生不同的热特性，最佳工作温度为15-35℃。当电池使用时，由于电池芯内发生化学反应，温度会升高。本文将进一步讨论在实际使用中不同温度下使用时电池组的特性。不同类型电池的使用在面对温度升高时具有不同的特性。与LFP相比，NMC电池具有更快的SOC降低和更高的发热量。
